context_page_description: Condensed aerosol fire suppression is a particle-based form of fire extinction. It is similar to gaseous fire suppression.
  It employs a fire-extinguishing agent consisting of: very fine solid particles as well as gaseous matter. The condensed aerosol microparticles and effluent gases are generated by the exothermic reaction; the particles remain in vapor state until the process of being discharged from the device. Then, it is "condensed" and cooled within the device and discharged as solid particles.
  Compared to gaseous suppressants and dry chemical suppression agents, the National Fire Protection Association defines condensed aerosols as those that release finely divided solids of less than 10 micrometres in diameter.
  The solid particulates have a considerably smaller mass median aerodynamic diameter than those of dry chemical suppression agents. The particulates also remain airborne significantly longer and leave much less residue within the protected area.
  Condensed aerosols are flooding agents. They are effective regardless of the location and height of the fire. This can be contrasted with dry chemical systems, which must be directly aimed at the flame.

  Compared to gaseous suppressants (which emit only gas) and dry chemical suppression agents (which are powder-like particles of a large size - 25–150 micrometres), the National Fire Protection Association defines condensed aerosols as those that release finely divided solids of less than 10 micrometres in diameter. 
  The solid particulates have a considerably smaller mass median aerodynamic diameter (MMAD) than those of dry chemical suppression agents. The particulates also remain airborne significantly longer and leave much less residue within the protected area. 
  Condensed aerosols are flooding agents. They are effective regardless of the location and height of the fire. This can be contrasted with dry chemical systems, which must be directly aimed at the flame. 
  The condensed aerosol agent can be delivered by means of mechanical operation, electric operation, or combined electro-mechanical operation.
  Wet chemical systems, generally found in foam extinguishers, must, similarly to dry chemical systems, be sprayed directionally onto the fire.
